MACHINE FOR MAKING SHOE-SOLES FLEXIBLE.

SPECIFICATION forming part of Letters Patent No. 593,827, dated November 16, 1897.

Application led April?, 1897. Seria] No. 631,091. (No model.)

To all whom t may concern:

Be it known that LLEWIS D. ZIEGLER, a citizen of the United States, residing inY the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Machines for Making Soles of Shoes Flexible, which improvement is fully set forth in-the following specification and accompanying drawings.

My invention consists of an improved conshoes iiexible, the novel features thereof being hereinafter fully set forth, and pointed out in the claims. p

Figure l represents a perspective view of a machine for making the soles of shoes flexible embodying my invention. Fig. 2 represents a transverse section of Fig. 1, the section beingtaken on line a; w of saidngure.

Similar letters of reference indicate corresponding parts in the figures.

'Referring to the drawings, A designates a machine for making the soles of shoes flexible, the same having its frame mounted on the base B, from which rise the standards C on either side thereof, and in the portions D of which is mounted the shaft E, which revolves in suitable bearings and carries the roller F, said shaft and rqller being rotated by means of the handle or crank-arm G or by other suitable means.

H designates a roller at the front of the machine, the same being mounted on the shaft J, whose bearings are on the frame of the machine. l Y

Kdesignates a'roller located in the rear of the roller F and mounted on the shaft L, which latter has its bearings in the arms M, it being of course understood that an arm is located on each sideof the machine, said arms being pivoted to the latter by the pins or bolts N.

P designates pins attached to the arms M and engaging the upright strips Q, each of which has a laterally-deiiected foot which is tends across the back of the machine'and is provided with the threaded stems S, which engage the bed B at their lower extremities, while their upper portions have the thumbnuts T mounted thereon, whereby the height of the cross-piece'R and the arms M can ybe adjusted according to requirements.

U designates a roller mounted below the roller FV rearward of the roller H and serving to assist in supporting the endless band or apron V, which, after passing by said roller U, passes around the roller W, which is located under the roller F and above the roller U, said band V passing thence partially around the roller F, thence over the roller K, and afterward over `the roller H toward the roller U, it being noted that the portion of the band intermediate the rollers F and H is doubled upon itself. v

4 Y designates a cross-bar suitably supported above the roller U, between which latter and said cross-bar the endless belt or apron V passes. 4

The operation is as follows: The sole Z is inserted at one end in the space between the cross-barY and the endless belt or apron D and then carried around the roller W, so as to be practically doubled upon itself, substantially in the manner indicated in Fig. 2, the direction of travel of the sole being indicated by the arrows in said figure and its movement being causedby its contact with the endless belt V during the rotation of the roller F in the direction indicated by theY arrows. After the sole has entirely passed around the roller W it may be readily removed from the machine.

It will be seen from the foregoing that the sole Z is subjected to compression and stretchingY for substantially every portion of its length, and is thus rendered exceedingly flexible and pliable after it leaves the machine.

The tension ofthe endless band V can be adjusted according to requirements by raising or lowering the arms M and with them the roller K, which can be eifected by the proper manipulation of the thumb-nuts T and the stems S.

It will be noted that the rollers H, F, K, and W decrease in .diameter in the order named, but I do not of course desire to be limited to such construction, nor do I limit the use of my invention to shoe-soles, as other shapes of leather are included therein.

IOO

Having thus described my invention, what said roller F and a roller K secured in the rear thereof, a roller IV located underneath said roller F, an endless apron passing around said rollers and the cross-bar Y adjacent said roller IV.

2. In a machine for making the soles of shoes flexible, a roller F suitably supported, rollers II and K mounted in front of and be hind said roller F, said roller K being mounted on adjustable arms M, a roller YV located in proximity to the roller F, a roller U located between said rollers IV and H, an endless apron passing around said rollers, and the cross-bar Y above said roller U.

3. In a machine for making the soles of shoes fiexible, a roller F suitably supported, rollers II and K located in front of and behind said roller F, arms M in which said roller K is journaled, means for raising and lowering said arms, a roller U, a cross-bar Y located above said latter roller, a roller IV located in proximity to said roller F and said cross-bar Y, and an endless apron passing around said rollers.

et. In a machine for making the soles of shoes iiexible, a roller F suitably supported,

means for actuating the same, a roller II located in front of said roller F, a roller K located behind the latter, arms in which said roller K is j ournaled, upright strips connected to said arms and resting upon a cross-piece R, means for adjusting the height of said cross-piece, a roller W located in proximity to the roller F, a cross-bar Y located adjacent said roller XV, a roller U located under said cross-strip and an endless apron passing around said rollers.

5. A machine for making the soles of shoes flexible, consisting of a base With standards mounted thereon, a series of rollers mounted in said standards, an endless apron on said rollers having a portion doubled upon itself, mechanism connected with and supported on said base for adjusting the tension of said apron and a cross-bar adjacent to one of said rollers and between which and said adjacent roller said apron and the sole or leather to be treated pass.
